Gewindebohrstange KE71TM – thread boring bar for inside threads, solid carbide with internal coolant (Teknik Makina)

Gewindebohrstange KE71TM engineered for internal thread production in CNC and turning applications, offering a compact 125 mm overall length and compatibility with 8 IR indexable inserts

• Solid carbide construction for long tool life
• Internal coolant for reliable chip evacuation
• Compatible with 8 IR indexable inserts
• Compact Ø7.8 mm shank with 125 mm length

Consistent internal threads for higher throughput

The KE71TM is designed as a compact thread boring bar that delivers reproducible inside threads while keeping machine time low. The solid-carbide body provides dimensional stability under load and reduces vibration, which supports tighter tolerances on threaded bores. With a nominal diameter of Ø7.8 mm and an overall length of 125 mm, the tool is suitable for confined bores where rigidity and precision matter. This combination of material and geometry translates into fewer rejects and more predictable cycle times, an advantage in batch production.

Coolant-through design that protects tool life and process stability

An integrated internal coolant channel ensures coolant reaches the cutting zone directly, improving lubrication and chip control. Better coolant delivery reduces heat build-up at the cutting edge and helps avoid built-up edge formation on inserts, extending the life of the indexable cutting tips. The coolant-through feature also supports consistent surface finish in blind or deep internal threads; as a result, rework is minimised and machine utilisation increases. The right-hand cutting orientation complements common spindle set-ups for straightforward integration.

Quick set-up and insert compatibility for efficient tool changes

The bar is prepared for 8 IR indexable inserts and is identified by the ISO designation E08K, making replacement and tooling standardisation straightforward. The mounting interface accepts an 8 mm shank (D = 8 mm) and the clamping system uses a Torx T6 fastener with screw size M2x4.6, enabling secure, repeatable clamping with minimal adjustment time. A modest mass of 0.045 kg means reduced centrifugal load in high-speed spindle applications, and the 5.3 mm cutting height supports robust engagement while maintaining chip control.

FAQ

What types of threads can be produced with this tool?
The KE71TM thread boring bar from Teknik Makina is intended for producing internal threads in through and blind bores where indexable insert threading is applicable.

Is the tool suitable for high-speed machining?
The solid-carbide construction and compact mass (0.045 kg) make the bar appropriate for higher spindle speeds, provided machine rigidity and recommended insert grades are observed.

Which inserts are required for mounting?
The bar is compatible with 8 IR indexable inserts and follows the E08K ISO designation for straightforward procurement and interchangeability.

Does the tool provide coolant supply to the cutting edge?
Yes; the KE71TM features an internal coolant channel to ensure directed coolant delivery to the cutting zone.

Can this bar be used in small-diameter bores?
With a nominal diameter of Ø7.8 mm and an 8 mm shank, the tool is designed for compact internal threading tasks where space is limited.
